- the invention relates to a construction of a naval independent Schlepp stresses as Matterwasserlos a device platform for the ultra-high-resolution 3D measurement of small structures in the seabed. Due to the construction of the floating body according to the SWASH (Small Waterplane Area Single Hull) principle (Abeking & Rasmussen), the buoyancy and gravity are below the sea surface and stabilize the float in the water.

- Marine detection system by an autonomous underwater vehicle with sonar.
- seismic in the context of seismic or seismic signal receivers, may be understood to mean any kind of instruments and measurements relating to seismics, generally referring to Wikipedia, namely seismics (also geoseismics) being a branch of applied geophysics and methods that explore and graphically map the upper crust by artificially induced seismic waves, distinguishing between land seismics used on the mainland and sea seismics applied to water surfaces.
- non-summative transmission of the measured values can or will be understood to mean an explicit, signal-related, separate transmission of measured values.
- online transmission of measured values or the term “online” can be understood to mean an operational connection via a communication network, in this case measured values.
- mothership as the vehicle in general, a larger vehicle such as a ship accompanying smaller vehicles such as a boat, submarine or the like can be viewed and used as a base, for example, for supply and repairs.

- Global Positioning System means the location of a device or subscriber in a system, for example GPS (Global Positioning System);
- Position and navigation information means the position and navigation information of a device or participant relative to a defined system, eg GPS (Global Positioning System); "position sensor” means the relative position of a device or participant relative to a defined one System measures and / or records;
- drive body - a three-dimensional body, the at least one drive

- the successful laying of the depth must be proven after completion of the work. Repeat measurements are to be performed every 2 years, later 4 years. Usual detection depths are between 0 - 6 m,
- Previous methods work with magnetic field measurement or acoustic measurement.
- ROV Remote Operating Vehicle
- the systems have a few meters wide survey compartments and are therefore vulnerable to course deviations due to current or pivoting of the cable route. Towed on the sea surface gear carriers are vulnerable to swell.
- the signal frequencies used in the kHz range it is necessary to determine the position of the receivers, which is at least centimeter-accurate, and which is difficult or impossible to achieve in normal swaying motion
- the magnetic field measurement for current-carrying cables fails due to the lack of predictability or evaluability of the expected anomaly. Magnetic field impressions introduced during cable production can only be measured in the de-energized state and allow detection only up to a depth of approx. 1.8 m. Especially in sandy areas, the cable can sag more often up to 2 m and is then no longer detectable with this method. Acoustical procedures have been able to map the cables well only on crossing profiles. Therefore, these measurements are only made selectively. Interpolation takes place between the measuring points taking into account the bending stiffness of the cable. Although the acoustic pangeo system is designed for profiled measurements along the cable route, it can only trace the burial depth along the cable route at points where the measurement conditions are optimum, due to the small fan width.
